smicIrrcnrrrolv forming part of Letters Patent No. 283,189, dated August 14, 1883.

Application flled June 28,1883. (No model.)

To all whom it may concern:

Be it known that I, AMY BARDEEN, of

` Blackstone, in the county'of VVorcestenState of Massachusetts, have invented a certain new and useful Improvement in Grain-Elevators, of which the following is a description sufliciently full, clear, and exact to enable any per-` son skilled in the art or science to which said invention appertains to make and use the same, referencebeing had to the accompanying drawing, forming a part of this specification, in

which the figure is a vertical transverse secJv tion representing' a s hip or vessel provided with my improvement.

My invention relates more especially to that class of grain-elevators which are used on shipboard for removing grain from the hold of the vessel; and it consists in a novel construction and arrangement of the parts, as

hereinafter more fully set forth and claimed, by which a more effective device of this character is produced than is now in ordinary use.

The nature and operation of the improve ment ,will be readily understood by all conversant with such matters from the following explanation, its extreme simplicity rendering an elaborate descriptionunnecessary.`

In the drawing, A represents the hold;B,

the'lower and C the upper deck of the vessel. D D on the deck C there is a shaft, E, provided with the centrally-arranged pulleyG, and a pulley, H, at'either end. A. shaft, J,

provided with a centrally-arranged pulley, K,

and the pulleys B l?, is journaled horizontally beneath the deck B in the lugs or arms L L, these arms being connected at their upper ends with the vertically-arranged screws M M,

i t. which work in corresponding nuts, N N, in the deck B. An endless belt, O, provided with buckets B, ypasses around the pulleys G'K, being arranged to work through the openings S S in the decks B C. w Disposed on the outer end of the shaft J there is a pulley, T, and journaled horizontally inthe bearings U U there is a shaft, W, provided with a rotary shovel, Y, and pulley Z, said pulley being connected with the pulley T by the belt Q.

In the use'of my improvement power is applied to the shaft E inthe ordinary manner by means of an engine and pulley, (not shown,)` causingsaid shaft torotate and communicate J ournaled horizontally in the standards motion through the belts F to the shaft J, and through the belt Q to the shaft W, causing the belt O and buckets R to traverse and elevate the grain from the hold' of the vessel, in a man ner which will be readily obvious without a more explicit description.

The object of the rotary shovel Y is to bring the` grain into such a position in the ,hold of the vessel as to be readily taken up by the buckets R, and for thatpurpose it maybe moved therein ofthe slides f, as desired, the

`belt Q being lengthened or shortened accordby the wheels h It, secured to theirlower ends,

the standards D D will be depressed or raised accordingly.

At the commencement of the operation of `discharging the vessel it will not be required to have the buckets R R enter the hold A to a great depth below the deck B,'and therefore i the wheels h on the lower ends of the screws c are turned to elevate the standards D and the wheels l on the upper ends of the screws M to elevate the tugs/L to bring the buckets into the desired position. i

Instead of one of the rotary shovels Y, the shaft J may be providedv with other pulleys and belts, and severalof said shovels operated at the same time in different parts of the hold to bring the grain" into proper position to be taken up dby the buckets B.

It will be obvious that by means of the screwsrM a the elevator may be vertically ad'- justed to any desired height. It will also be understood that proper hatchways or apertures are to be provided in the decks to enable the belts F O to be properly worked.

Having thus explained my invention, what I claim isl. The improved grain-elevator herein described, the same consisting of the shaft E, provided with the pulleys H G, the shaft J, provided with the pulleys K l), the lugs L, provided with the screws M and wheelsl, the standards D, provided ,with the screws c and IOO ' Wheels h, the belt o, provided with the buckets R, and the belts F, constructed, combined, and arranged to operate substantially as set forth.

2. In a device for removing grain from the llold'of a vessel, the shaft E, ,provided with the pulleys H G, the shaft J, provided with the pulleys K l?, the lugs L, provided'with the screws M and Wheels Z, the ystandards D, pro- Y Io vided with the screws a and wheels 71 the belt O, provided with the buokets'R, the shaft W, standards U, slides f, shovel Y, pulley Z, and belts Q F, all constructed, combined, and a1'- ranged to operate substantially as and for the purpose specified.
